How to Maintain Lamp
Life
There are some actions that can shorten lamp life:
• Turning off AC power when the lamp is on. (Turn off the lamp with the remote and let it
cool until the fans stop; then turn off AC.)
• Turning a lamp on and off rapidly. (The lamp should be allowed to heat up fully before
turning it off, at least three minutes.)

Filter Replacement
Clean, cool air is essential for proper VideoWall/CineWall operation.
When the air filter gets dirty, change it. Unfortunately, there is no absolute rule about
when to change an air filter. For some installations the environment has clean, dust-free
air, in which case the air filter may be good for a year or more.
In other environments, the air full of dust and dirt all the time. The air filter might have to be
changed every month. Of course, it also depends on how many hours per day or per
week the lamp is on.
Determining a Changing
Schedule
Remove and inspect the air filter after three months of operation. Make a note of the air
filter’s condition. Check it again after six months of operation.
These two inspections will give you some idea of how often the filter needs changing. If it
doesn’t need changing after six months, inspect it again in a year. As long as the
environment doesn’t change, you can build an appropriate schedule in this way.
If new construction occurs in the vicinity of the VideoWall/CineWall, beware; new
construction usually means DUST.
Removing the Air Filter 1. Open the screen.
2. Turn off the AC power switch and remove the power cord.
3. Lift the air filter up and toward you. Then, replace it with a new one (Runco part
number 379-0012-00).
➤
If the lamp cable is not fully seated on the lamp plug, the lamp will
not operate properly. Overheating may occur.
